This XSeries P320 features the full-length XFULL slide and 4.7 in barrel, delivering the full-size sight radius and 17+1 capacity that many shooters prefer. It is striker-fired and equipped with a flat-faced, skeletonized trigger for a consistent, straight-back press. Controls include a standard left-side magazine release and bilateral slide-catch levers.
The slide is finished in black with forward and rear cocking serrations and an optics cut. A SIG Sauer ROMEO-X red dot is installed on the slide; the rear sight is removed for the optic, and the cover plate is not present because the optic occupies the cut. A green-ringed front post remains in place for a clear reference point.
The XSeries grip module provides aggressive texturing, an extended beavertail, and a high undercut for a secure, high grip. The black polymer frame integrates a 3-slot M1913 accessory rail. The overall configuration is the XFULL PRO variant within the P320 XSeries line.
Built on SIG’s modular P320 fire control unit, this pistol uses a stainless steel receiver marked Newington, NH, USA. The FCU serial is visible. Country of origin is USA. This pistol was issued for Law Enforcement personnel, and this surplus model has been made available to the civilian market.
